Windows phone如何检测来电

using Microsoft.Phone.Tasks;
using Microsoft.Phone.Controls;

// 注册电话状态事件
PhoneCallManager.PhoneCallReceived += PhoneCallManager_PhoneCallReceived;

// 电话状态事件处理程序
private void PhoneCallManager_PhoneCallReceived(object sender, PhoneCallReceivedEventArgs e)
{
    // 处理来电逻辑
}

using Microsoft.Phone.Tasks;
using Microsoft.Phone.Controls;

// 检查电话通话状态
PhoneCall call = new PhoneCall();
if (call.State == PhoneCallState.Ringing)
{
    // 处理来电逻辑
}
